Fabric softener vs wool dryer balls: which one belongs in your laundry room?
One is in nearly every UK trolley. The other costs about a penny per load and adds nothing to your bedding but softness. We spent six weeks and forty washes finding out which deserves your money.

The short answer
Wool dryer balls win for most homes. They soften nearly as well, cost 40× less over a year, and leave nothing on the fabrics you sleep in. Softener keeps its place only if scent is the whole point for you.
Head to head
The common pick
£3.50 · 1.16L
Supermarket Fabric Softener
★★★☆☆ 3.1 / 5
Instant softness and a strong scent, but it works by coating fibres, which builds up on towels and bedding, and the fragrance is where most skin irritation hides.
The better alternative
Our winner
Pure Wool Dryer Balls, set of six
★★★★½ 4.6 / 5
100% wool, nothing else. They lift and separate fabric as it tumbles, giving softness without residue, around 20 minutes off drying time, and they last a thousand loads.
Prices checked 24 July 2026 and may have changed.
The verdict, at a glance
Our winner
Wool Dryer Balls
Meets our safe-home standard
What we love
✓
Nothing touches your skin but wool
No perfume, no quats, no preservatives. Softness comes from motion, not coating. Ideal for sensitive skin and children’s bedding.
✓
Roughly a penny per load
One set replaced £47 of softener across our six-week test, and it’s still going.
✓
Cuts drying time by ~20 minutes
They open up the load so warm air circulates. Less energy, less wear on fabrics.
✓
Towels stay absorbent
No waxy build-up means towels keep doing their job, which is obvious by week three.
Worth knowing
✕
No scent, unless you add one
If a fragranced airing cupboard is the point for you, you’ll need a few drops of essential oil, or a linen spray after.
✕
Tumble dryer only
Line-dry your laundry? These do nothing on the washing line.
✕
They thud, gently
A soft rhythmic tumble noise. Fine in a utility room; noticeable next to the sofa.
The verdict
For most homes, the quiet upgrade wins.
For anyone with sensitive skin, young children, or a decent tumble dryer, wool dryer balls are cheaper every single month, kinder to fabric, and add nothing to the sheets you sleep in. Keep softener only if scent is really the point, and even then, consider moving it away from bedding.
